My Research Works

An Analysis on Structural MRI Images for Better Alzheimer Disease Detection using Deep Neural Networks

Rifat Arefin*, Nazia Jahan Khan Chowdhury, Saurav Roy, Md. Zahim Hassan

The objective of the research work is to classify different stages of Alzheimer's Disease from structural MRI using CNN based model. This research work has been presented in the International Conference on Computing Advancements (ICCA), 2024. This study enhances Alzheimer’s disease classification by applying pre-processing techniques to structural MRI images and using pre-trained models like VGG16, ResNet50, and MobileNet. Using the OASIS dataset, MobileNet achieved the best results, showing that pre-processing significantly boosts classification performance.
